The firm’s Chief Risk Officer John Hogan will take a temporary leave for personal reasons starting later this week, according to a memo to staff, saying that, “I’m looking forward to taking this time off to spend with my family and friends.” Deputy Risk Officer Ashley Bacon will fill in until Hogan returns in the summer. Hogan, had previously served as chief risk officer for the investment bank, taking that post a year ago, some three months before JPMorgan reported a large and illiquid trading position at the chief investment office.

Sources report that JPMorgan analysts Yoshiharu Izumi and Nobuhito Owaki, based in Tokyo, are exiting the firm, says Bloomberg. Izumi is an executive director who managed industrial and consumer electronics firms, and Owaki was a chemicals analyst.
